SPECIFICATION forming part of Letters Patent No. 498,581, dated May 30,1893.

Application filed May 23, 1892.

To all whom it may concern.-

Be it known that I, JAMES SHAND, a citizen of the United States,residing at Detroit, in the county of \Vayue and State of Michigan,

have invented certain new and useful Improvements in Carriage-Poles, ofwhich the following is a specification,reference being had therein tothe accompanying drawings.

This invention relates to new and useful to improvements in carriagepoles, and the invention consists in the peculiar construction of anadjustable extension for a circle bar, and further in the peculiarconstruction, arrangement and combination of the various I 5 parts, allas more fully hereinafter described.

In the drawings, Figure 1 is a plan View of a vehicle pole embodying myinvention. Fig. 2 is an enlarged, central, horizontal section throughone of the extensions of the circle bar.

In the present state of the art carriage poles have been made withdifferent forms of adj ustment, but so far as I am aware all suchadjustments embody some kind of a clamping device, which must beloosened when the connecting part of the pole is desired to be adjusted,and must be tightened when it is desired to be secured in its adjustedposition. My invention consists in so constructing the extensions of thecircle bar or cross bar arms forming part of said extensions that theyare locked at every point in the adjustment.

A is the pole, the rear end of which alone is shown. This pole issecured to the cross 5 bar or circle bar B, which is braced in anysuitable manner by the braces 0. At each end of this circle bar I formthe adjustable extension, and as both ends are alike, a description ofone will suffice for both. The extension preferably consists of twoparts, the part D which I will call the socket iron,

as it is usually constructed of a socket, or is bifurcated to receivethe end of the circlebar, being secured thereto by means of bolts,

E. In the drawings, I have shown these bolts also securing the ends ofthe braces, but this is immaterial. This socket iron is provided with apivot plate F.

G is the other end of the extension, which I will call the adjustablearm. This arm is bifurcated at its outer end to embrace the fierial No.484,020- (No model.)

pivot plate F and the two are pivoted together by the pivot 11.

The arm G at its inner end is provided with the bearing block I pivotedthereto in the usual manner and adapted to engage with the ordinary drawjacks on the axle I.

The arm G at one side is provided with the bifurcated extension J at theupper end of which is the cross bar or bolt K. The socket iron isprovided on the same side with the off-sets L separated a short distanceand apertured to receive the bolt M, which passes through both aperturesand through the nut N between the two off-set portions. The bolt and nutare suitably screw-threaded so that by turning the out which bears eachside against the ofi-set portion, the bolt will be adjusted in or out.The bolt at its outer end is provided with a slotted head 0, thecrossbar K engaging with the slot therein. The parts being thusconstructed, in order to adjust the arms G toward or from each other tofit the vehicle to which the pole is to be attached I turn the nut Ninadirection desired, retracting or extending the bolt M, which actingthrough the off-set J will move the arm G to the desired position, andit is evident that as the nut will lock the bolt at any desiredposition, no tightening or loos- 8o ening of clamping parts is requiredin making the adjustment, enabling me not only to effect the adjustmentquickly, but also pre venting the possibility of any parts rattling, andalso obviating the difficulty which would arise in casea clamping boltwere used and in case such clamping bolt became loose which isfrequently the case.

tVhat I claim as my invention is l. The combination with the pole, thecircle 0 bar and adjustable arms at the end of the circle bar, of ascrew bolt extending from the adjustable arm to the circle bar and a nutfor adjusting said bolt engaging between the two stationarybearings,wherebythe arm is locked at every point of adjustment,substantially as described.
